Add LO offset support.
Only set tx/rx_bandwidth after getting tx stream, to reduce TX LO leakage for <10MHz bandwidths.
Check for reference and LO lock before getting streams.
Set bit size to be 16 for interpolators and decimators.
Match buffer size to UHD.
Don't destroy TX stream, as there appears to be a bug when recreating it.
Catch exception when checking for TX underflow.
Increase RX FIFO size, to reduce overflows at high sample rates.
Allow RX to continue streaming after receiving timeout.
